What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

Researchers are testing whether drinking whey or pea protein before moderate-intensity aerobic exercise changes blood sugar levels and appetite in adolescents with type 1 diabetes. Thirty teens will each try four conditions: a low and a moderate dose of whey protein and a low and a moderate dose of pea protein. Participants drink the protein 45 minutes before a supervised 45-minute workout, wear a continuous glucose monitor, and rate their hunger and fullness. The goal is to learn whether the type and amount of protein before exercise can help manage blood sugar and appetite around workouts.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
whey protein and pea protein drinks
What this could lead to
If protein before exercise helps steady blood sugar, teens with type 1 diabetes could gain a simple, food-based way to make workouts safer and easier to manage.
What could go wrong
This is a small, short-term study of 30 teens, so results may not apply to everyone or last. Protein drinks can affect blood sugar unpredictably, and exercise itself carries a risk of low blood sugar.
